Please note that we strive to make this event affordable and do not require payment in advance based on our alumni trust and volunteerism. Onsite registration will be $15 per adult and is not recommended because we need time and budget to prepare food. If you need to cancel your registration, please do inform us at least two days ahead of the event to prevent any food waste and your credibility damage (Those who get registered but fail to show up will be blacklisted and publicized).
